Fluid and vapor hoses. What should I use? How should I clamp them.
Many aftermarket and even OEM parts, like fuel pumps, transmission coolers, and inline filters, ship with the wrong hoses and cheap incorrect clamps causing more than a little trouble when they fail prematurely on parts like in-tank fuel pumps that are not very accessible. SAE the Society of Automotive Engineers is a standardization organization that publishes engineering specs for various automotive and industrial systems. You can search for free overviews of the SAE standards by J number on this page http://standards.sae.org/ Complete white papers can be purchased but they're pretty dry reading. Most of the larger name hose manufacturers, Goodyear and Gates to name a few, make hoses that specifically meet various SAE standards. When the J-number is printed on the hose you know exactly what that hose was designed to do. Hopefully this is useful to someone. -SAE J30 http://standards.sae.org/j30_199806/Fuel System Hoses SAE J30 is the SAE standard prefix for fuel hoses. The suffix letter and number gives application specifics. -SAE J30R6 Fuel Filler Hose http://www.goodyearrubberproducts.co...s/page0033.pdf Application:Flexible connection between the rigid filler neck and tank. -SAE J30R7 PCV Emission Control Hose http://www.goodyearrubberproducts.co...s/page0031.pdf Application:WARNING: DO NOT USE J30R7 HOSE FOR FUEL INJECTION LINE OR WITH BIODIESEL.A multipurpose fuel resistant hose. Use for PCV and Charcoal purge lines.Specific Fuel: -SAE J30R9 Fuel Injection Hose http://www.goodyearrubberproducts.co...s/page0032.pdf Application:WARNING: DO NOT USE J30R9 HOSE FOR FUEL PUMPS INSIDE FUEL TANK.Fuel Injection Hose Designed specifically for auto and truck fuel injection systems. Should also be used as low pressure fuel line and fuel vapor recovery line. J30R9 has a better vapor barrier than J30R7.Specific Fuel:Gasoline, ethanol extended gasoline (E10, E-85), oxidized sour gas, diesel fuel, biodiesel.Specs:Working pressure 100PSI -J30R10 Submersible fuel injection hose.http://www.gates.com........submersible-fuel-line-hose Engineered for constant contact with fuels on the inside and outside. Application:NOTE: Many fuel pumps including units from trusted manufacturers ship with hoses not labeled J30R10. Nowhere in their documentation do they state the included hoses meet this standard. I've had these un-marked hoses split on a car. I had to drop the tank a second time to put in the right stuff. It's far easier to buy hose you know won't fail in service.Fuel Hose capable of handling gasoline, alcohol-extended gasoline or diesel fuel in fully immersed, mobile, stationary and marine applications. -6.2L & 6.5L Diesel Injector Return Hoses Nitrile Butadiene Rubber >NBR< Fuel Hose with Black Woven Cover capable of handling low pressure diesel without clamps. ![]() OEM GERMAN >NBR< Black Woven Cloth Covered Nitrile Butadiene RubberApplication:
